Ryu's Final Smash

Notes:

Ryu's Final Smash looks to be the Shin Shoryuken, probably meaning it's something akin to Mac's KO Punch -- possibly evidenced by how Mac is the victim in this trophy.

Edit: Voice clips released also lead to speculation that he might fire a Shinku Hadokuen first -- either that or it's possible to use one or the other, which would be a first for a Final Smash.
